According to Dr. Kwan, the changes might include:
• a larger head to accommodate a larger brain
• larger nostrils for easier breathing in off-planet environments
• denser hair to contain heat loss from a larger head
• eyes getting larger, as attempts to colonize Earth’s solar system and beyond see people living in dimmer environments farther away from a sun
• skin becoming more pigmented to lessen the damage from harmful UV radiation
